If you are required to use this specific portal and cannot switch, you can optimize your environment to achieve better performance:
Webbudtvultra.com sounds unfamiliar. Maybe it's a niche site or a typo. "Webbudtvultra" could be a combination of "web," "buddtv," and "ultra," but it's not a known website. The user wrote indexsphp, which is a typo. The correct path is index.php. So the actual URL might be http://webbudtvultra.com/index.php.
Large CSS, JS, or image files loaded via index.php without minification, bundling, or lazy loading will bloat page size. For a TV site, video thumbnails and players amplify the problem.
